交叉参考的相关申请本申请涉及美国临时专利申请号60/290,117题为“异类的视觉可变的水性墨水的成分”和申请号60/289,989题为“适用于喷墨打印机的同类感光性视觉可变墨水的成分”,并已委托予本发明的受让人,已于2001年5月10申请。 CROSS REFERENCE TO RELATED APPLICATIONS This application is related to U.S. Provisional Patent Application No. 60 / 290,117, entitled "optically variable component of the aqueous ink heterogeneous" and Application No. 60 / 289,989, entitled "grade suitable for inkjet printers photosensitive visually change ink composition ", and has been entrusted to the assignee of the present invention, in 2001 May 10 to apply.

发明领域本发明主要涉及一种物件的鉴定,例如,钞票、证书和邮资、特别涉及通过确认上述物件所提供的安全标志来鉴定该物件。 Field of the Invention The present invention generally relates to identifying one object, for example, banknotes, postage certificate and, in particular, relates to the article identified by the security flag confirm the above object is provided.

技术背景众所周知,通常是采用对在可视光谱内具有高反射对比度的图像敏感的自动检测仪,用于机器处理各种类型携带信息的票据,标签,商标,邮资及类似安全标志。 BACKGROUND ART known, usually by an image having a high reflectance contrast in the visible spectral sensitivity of the automatic detector configured to carry various types of bill handling machines, Labels, safety signs postage and similar information. 另外,众所周知,也可以采用对能产生较短波长的激发(例如,紫外(UV)激发)的安全标志的荧光发射敏感的自动检测仪。 Further, it is known, may be used to produce fluorescence excitation of a shorter wavelength (e.g., ultraviolet (UV) excitation) security flag automatic transmission sensitive detector. 例如,在邮资计量的领域中,邮件携带采用荧光墨水印刷的邮资邮戳可增加邮件的机器处理。 For example, in the field of postage metering, the mail processing machine using fluorescent inks carrying postage indicia printed messages increase. 在美国和加拿大,自动设备可通过检测黏附在邮件上的邮资邮戳的红色荧光来适当地面对着或确定各个邮件的方向。 In the United States and Canada automatic equipment can be appropriately adhered facing direction or in individual messages to determine the red fluorescent postage indicia on the mail by detecting. 邮资服务面对设备采用简单的检测仪来定位荧光。 Postal services face a simple device to locate the fluorescence detector. 该检测仪不能确定荧光和邮戳的图像是物理相一致的,于是就限制了检测仪确定安全标志的鉴定能力。 The detector can not determine fluorescence and the indicium image are physically coincident, thus limiting the flag detector secure identification capability. 正如本文所使用的,术语“红色荧光”并不是指墨水的可见颜色,而使之在光谱的红色区域中的荧光。 As the term "red fluorescence" as used herein does not refer to the visible color of the ink, so that the fluorescence in the red region of the spectrum.

正如本文所使用的,“荧光安全标志”是指在光谱的定义区域中可暴露于较短波长激发光(例如,UV光)的荧光的安全标志。 As used herein, "fluorescent security mark" refers to a defined region of the spectrum may be exposed to the shorter wavelength of the excitation light (e.g., UV light) of the fluorescent security mark. 在入射激发光和荧光发射之间波长中的变化可以清晰地区分荧光和直接反射。 The incident excitation light and fluorescence emission wavelengths may change between clearly distinguish between direct and reflected fluorescence. 荧光安全标志可有效地应用于伪造票据,有价证券,身份证,证券纸等等的检测。 Fluorescent security mark can be effectively applied to detect counterfeit notes, securities, identity cards, security paper or the like. 复制安全标志的荧光的困难阻止了复制并且提供了赝品的法律证据。 Hard copy safety signs fluorescence prevents replication and provide legal evidence of fakes. 在这些应用中,安全标志是条款的检测,产生的标志,以及自动条款的识别。 In these applications, terms of safety signs are detected, marking produced, as well as automatic identification provision. 对这些应用来说,荧光的亮度是重要的。 For these applications, the brightness of the fluorescence is important.

伪造者没有采用具有机读荧光墨水的打印机,而是通过在荧光的背景上复制标记或者在复制的标记上涂覆荧光材料的方法,就能够产生可发出荧光并可机读的安全标志。 Forger does not use a printer having a machine-readable fluorescent ink, but by copying the background fluorescence marker or markers in the method of the fluorescent material coated on the copy, it is possible to produce and emit fluorescent security mark machine readable. 在这两种情况下,原始的和复制的标记是可识别的。 In both cases, the original and copied indicia are identifiable. 一个法律验证系统可以产生这样的识别,正如本文所讨论的。 A legal verification system can generate such an identification, as discussed herein.

手动的法律检测系统可以简单的是一个可视光源和一个紫外光源,还具有一个可在这两种光源之间切换的开关。 Manually law detection system may be simply a visible light source and an ultraviolet light source, further comprising a switch switchable between the two light sources. 操作者可以观察在这两种光源下的标记,并且在紫外光的照明下验证图像的荧光和背景的没有荧光。 The operator can observe the mark in both the light source and verified under UV illumination and fluorescence without background images.

当采用可视光源来照明一个原始的安全标志时,与纸张的发亮背景相比照,图像是发暗的。 When the visible light source to illuminate an original safety signs, illuminated with the background as compared to the paper, the image is dark. 当采用紫外光源来照明原始的安全标志的图像时,则与纸张的低荧光背景相比照,图像是发亮的。 When the ultraviolet light source to illuminate the image of the original safety signs, according to the low fluorescence background of the paper compared to the image is illuminated. 同样,采用可视光来照明一个复制的安全标志相对于发亮的背景显得较暗。 Similarly, using visible light to illuminate a safety mark appear darker copy respect bright background. 与在紫外光照明下的原始安全标志的图像性能相比较,印刷在荧光背景上的复制安全标志或采用荧光材料覆盖印刷的并采用紫外光照明与发亮的荧光背景相比照就显出暗的图像。 Performance in comparison with the original image at the safety signs ultraviolet illumination, background printed on a fluorescent marker or replication security printing using a fluorescent material covers and illuminated by UV illumination and fluorescence background would show as compared to dark image.

旋转的和其它凸版印刷机的邮资计量采用浸渍泡沫海绵或其它多孔媒介中的墨水的滚筒在信封上留下邮戳。 Postage metering and other rotary letterpress printing using a sponge roller impregnated foam or other porous media in the left ink indicia on the envelope. 适用于凸版印刷机计量的红色荧光复制的墨水包括工色、蓝色、绿色和黑色的墨水。 Red fluorescent ink suitable for copying measured include letterpress printing workers, blue, green and black ink. 例如,美国专利号2,681,317;2,763,785;3,230,221;3560,238;3,928,226和4,015,131披露了适用于该目的的红色墨水。 For example, U.S. Patent Nos. 2,681,317; 2,763,785; 3,230,221; 3560,238; 3,928,226 and 4,015,131 disclose red ink suitable for this purpose. 一般来说,这些墨水含有低蒸发压力的非水性的基于溶剂的媒介物体系,并具有高的固体浓度、高的粘性、高的沸腾温度和低的表面张力。 Generally, these inks contain a low vapor pressure non-aqueous solvent-based vehicle systems, and has a high solids concentration, high viscosity, high boiling temperature and a low surface tension. 凸版印刷技术缺乏印刷可变信息的数字印刷的能力。 Letterpress printing techniques lack the ability to print variable information in digital printing. 因此,这些凸版印刷机的墨水就不能用于喷墨打印机,因为这些墨水需要稳定的溶解度或随小颗粒的稳定流动性,低的粘性和特殊的表面张力。 Thus, the letterpress printing ink jet printer can not be used, because these inks require a stable solubility or with a steady flow of small particles, low viscosity and specific surface tension. 在目前的压电式喷墨打印机中,液体墨水的粘性可以从大约1.5到15厘泊(cps),而在热敏喷墨打印机中则为从1至5cps。 In the present piezoelectric inkjet printer, the viscosity of the liquid ink may be from about 1.5 to 15 centipoises (CPS), and compared with the thermal ink jet printer from 1 to 5cps. 喷墨打印机墨水的表面张力希望是在30至50dynes/cm之间。 The surface tension of ink jet printer is desirable between 30 to 50dynes / cm at. 在美国专利号5,681,381中披露了一种红色水性红色荧光墨水的例子,所披露的墨水符合适用于邮资的USPS的需要,同时还兼容于在喷墨打印机中的使用。 Discloses an example of a red fluorescent red aqueous ink in U.S. Patent No. 5,681,381, the disclosed ink applied to meet the needs USPS postage, it is also compatible for use in an inkjet printer. 这些墨水在有效期间是稳定的。 These inks validity period is stable. 这些墨水的主要成分是基于说,辅助溶剂以及水溶性荧光调色剂的渗透性溶液。 The main components of these inks are based on said permeability, and water soluble co-solvent solution fluorescent toner. 这些墨水可设计成通过限制光学的限制来获得所需的荧光强度,使之光学强度低于机器阅读所需的正常强度。 These inks may be designed to obtain desired fluorescence intensity by the optical limiting restriction, so that the optical intensity lower than the intensity required for normal reading machine.

已经开发了邮资邮戳和邮资机器,这些设备采用了数字打印特别是喷墨打印。 We have been developed and postage indicia postage machine, which device uses a particular digital printing ink jet printing. 一个实例是由美国Pitney Bowes公司(Stamford,Connecticut,USA)所制造的个人PostTM邮资计量设备。 One example is personal PostTM postage metering equipment from the United States Pitney Bowes Company (Stamford, Connecticut, USA) manufactured. 众所周知,在业内,常常是使用数字打印机来打印具有有效日期的红色及红色荧光的邮戳。 It is well known in the industry, often using a digital printer to print red and red fluorescence with a valid postmark date. 数字打印邮戳提供了明显超越凸版印刷邮戳的优点。 Digital print postmark provide advantages beyond the obvious relief printing postmark. 喷墨打印提供了一种打印具有高密度可变信息邮戳的手段。 Ink-jet printing is provided a means for printing variable information indicia having a high density. Pitney Bowes'PostPerfect计量通过热传移打印的方式来产生具有有效日期的红色、红色荧光邮戳,而个人邮件办公装置可通过喷墨打印来产生红色及红色荧光邮戳。 Pitney Bowes'PostPerfect measurement to generate red, red fluorescent indicia have an effective date and thermal transfer printing by means of which the individual message office device may generate red and red fluorescent indicia by ink jet printing. USPS IBIP程序可允许使用黑色、可机读的邮戳。 USPS IBIP program may allow the use of a black, machine readable indicia. 邮局办公设备一般都是使用面对可识别标志或通过附加在邮戳上的荧光标签来调整携带着IBIP邮戳的邮件方向。 Office equipment is generally used in the post office can face identification or to adjust the carrying direction IBIP Mail postmarked by attaching fluorescent tags on the postmark. 邮资服务器可采用适用于增值服务、适用于邮戳的密码鉴别和适用于获得标志信息的各种可机读变化信息。 Postage server can be applied to value-added services, cryptographic authentication is suitable for machine-readable postmark and change information for a variety of signs to get information. 与凸版印刷技术相比较,数字印刷机可以在不减少印刷次数的条件下提供印刷的质量和对比度。 Compared to the relief printing technology, digital printers can provide print quality and contrast without reducing the number of prints. 该图像可以采用直接非接触的打印头以高的精度、高的质量和高的速度的方式来打印。 The image printing head may be employed directly in a non-contact manner with high accuracy, high quality and high speed printing. 这些墨水还具有适用于安全标志的其它优点,因为它们可以含有渗透性溶液使得荧光的成分可以有选择性地渗透到纸张中。 These inks have additional advantages for secure flag, because they may contain a solution such that the permeability of the fluorescent component can be selectively penetrate into the paper. 该选择性的渗透对安全标志的荧光成分提供了摹拓和伪造支票的抵制。 This selective penetration of the fluorescence components of safety signs provide forged checks and rubbing resistance.

用于邮票邮资所使用的喷墨打印的另一问题是现在由于缺乏同时适用于邮资和机读的喷墨技术的墨水功能而受限于某些范围。 Another problem for the postage stamps used in ink jet printing inks are now due to lack of postage available for both machine-readable and inkjet technology being limited to some range.

邮资服务采用在邮戳中印刷信息,以用于安全和标志目的的以及处理邮件。 Postage indicia printing service using the information, and to sign for security purposes and to process messages. 特别是,USPS的基于信息的邮戳以一个两维条形码的形式包含着高密度、可变化、加密保护的信息。 In particular, the USPS Information Based Indicia information comprises a two-dimensional bar code in the form of a high density, can vary, cryptographically protected. 为了能采集这个信息,邮资扫描设备必须有效检测和读取基于信息的邮戳,在各种基底上所印刷的邮资邮戳必须在反射方面具有足够的对比度,从而使邮戳能够机读。 In order to capture this information, postal scanning equipment must efficiently detect and read the information-based indicia, on various substrates printed postage indicium must have sufficient contrast in terms of reflection, so that can be machine-readable postmark. 例如,在暗的基底上,如反射比在0.45至0.6之间的牛皮纸信封,采用红色墨水就很难获得所需要的对比度。 For example, on a dark substrate, such as Kraft envelopes between the reflectance from 0.45 to 0.6, the use of red ink is difficult to achieve the desired contrast. 因此,就非常需要能印刷呈现出高对比度的安全标志,最好是黑色以及同时具有红色的荧光。 Therefore, it is highly desirable to be able to print high-contrast exhibit safety signs, preferably black, and also has a red fluorescence. 然而,红色荧光墨水通常并不具有光学特性识别(OCR)设备、条形码阅读机和其它类型的机器视觉技术能可靠阅读的足够对比度。 However, the red fluorescent inks typically do not have an optical characteristic recognition (OCR) equipment, bar code readers and other types of machine vision technology can reliably read a sufficient contrast. 这些系统一般在频谱的红色区域中具有照明和检测系统。 These systems typically have illumination and detection systems in the red region of the spectrum.

荧光安全性能的一个缺点是很多类的商品化有机发光化合物。 One disadvantage of fluorescent security properties are commercially available many types of organic light-emitting compounds. 普通的例子是发光的和商品化颜料荧光的材料和墨水。 Common examples are commercial pigments and luminescent materials and fluorescent inks. 邮戳的伪造复制就只能希望所采用的正是材料的基底具有能发射出类似颜色光的发光物质。 Indicia forgery copy can only hope that the substrate material is employed having a light-emitting substance can emit light of a similar color. 于是,这就有利于提供具有独特光学特性并不能采用简单的商品材料来模仿的发光墨水。 So, which is conducive to providing a unique optical properties can not be a simple light-emitting ink material product imitation. 本发明提供了具有这类独特光学特性的墨水。 The present invention provides an ink having such unique optical characteristics.

此外,在基于数字邮戳的邮件安全系统中,如果在多个邮件上复制和产生邮资邮戳,就很难使得邮资服务器可以知道在具有相同邮戳的邮件中那一个具有最初的邮戳。 In addition, the digital postmark-based message security system, if the replication and production of postage indicia on the number of mail, it is difficult to make postage server can know the one with the original postmark mail with the same postmark in.

于是,提供一种在邮件上附加一个安全且该安全随后可以用于在正当付费的邮件和没有付费的邮件之间识别的方法和系统是有利的也是需要的。 Thus, there is provided a safe and that an additional safety can then be used in a method and system for identifying the mail and paying between legitimate mail is not paid advantageously also needed on the message.

发明内容 SUMMARY

本发明的主要目的是使用一种难以复制的安全标志来鉴定一种物件,例如,邮件。 The main object of the present invention is the use of a difficult to replicate the security marker to identify one item, e.g., messages. 该安全标志可以是邮票和邮戳和其它印刷图像。 The safety signs can be a postmark and stamps and other printed image. 这一目的可以通过使用能够吸收可见光以及在紫外激发下产生荧光发射的墨水提供安全标志来获得。 This object is capable of absorbing visible light and generating using ink emitted fluorescence under UV excitation to provide safety signs obtained.

这种不是通常有效的墨水性能是同时存在着视觉上不同于荧光颜色的暗色(较佳的是黑色)和荧光。 This is not normally effective while there is ink performance dark (preferably black) and the fluorescence differs from the fluorescence color visually. 这类性能属于不闪光的、光敏感的光学可变器件(OVD)类别,这是难以伪造的。 Such properties do not belong to flash, light sensitive optically variable device (OVD) category, which is difficult to counterfeit. 当采用可见光照明时,OVD类别产生正常的发黑的现象,而在UV光的照明时,则产生红色的荧光。 When using visible light illumination, an OVD types produce normal blackening phenomenon, and when the illumination of UV light, the red fluorescence is generated. 在确定好的条件下,这种差异是可以预测的、可逆的和重新产生的。 In determining a good condition, this difference is predictable, reversible and regenerated. 主题发明提供了一种墨水,该墨水可以发出红色荧光并且也在整个可见光谱中具有高的光学密度通量,使得它即可由操作人员来读取也可由机器视觉系统来读取。 The subject invention provides an ink, the ink may be the entire red fluorescence spectrum and also has high optical flux density can be seen by the operator so that it can be read also read by a machine vision system. 由黑色颜色所提供的高对比度允许采用商用扫描仪来扫描采用这种墨水印刷的图像文件和邮戳,即使是在诸如牛皮纸信封的这类暗色的信封上。 A black color is provided using a commercial high contrast allows the scanner to scan the printed with this ink and the indicium image file, even in the dark such as manila envelope of the envelope. 所有波长的吸收使得在普遍存在的牛皮纸、棕色的信封上的形成在红色滤波器和红色照明下能获得所需的对比度。 All absorption wavelength so ubiquitous kraft paper, a brown envelope formed under the red filter and red illumination to obtain desired contrast. 这类OVD性能能够集成在文件中,因为它们呈现出正常的黑色。 Such OVD performance can be integrated in the document, since they exhibit the normal black. 因此,该OVD可以是隐蔽的安全标志,似乎从普遍存在的黑色印刷中难以区别,但是隐含着荧光的特性。 Thus, the OVD can be hidden safety signs, it seems difficult to distinguish from the ubiquitous black printing, but implicit characteristic fluorescence. 制造和提供这些光敏光学可变墨水的控制提供难以检测复制的一个明显的障碍。 And manufacturing these photosensitive optically variable ink is controlled to provide a significant obstacle difficult to detect replication.

图1b说明了非邮件的物件30,例如,票据、标签、流动券、支票、证书、身份证章或证书、文件或其他相类似的。 Figure 1b shows the non-mail items 30, for example, bills, labels, mobile coupons, checks, certificates, identification badges or certificates, or other similar documents. 例如,安全标志可以在非邮件物件30提供安全标志,如,一个或多文字数字符号34,一个图形设计32,一个目标36的相似形,一个条形码38。 For example, the security mark may be provided in a non-secure flag message object 30, e.g., one or more alphanumeric characters 34, a graphic design 32, a target 36 of similar shape, a bar code 38. 可以采用类似于在邮件上的安全标志的方法进行比较安全标志所产生的可见光图像和荧光图像来确认在非邮件物件30上的安全标志。 It may be similar to that visible light image and fluorescent image safe flag generated in the process of the security mark on the security messages be confirmed on the non-mark message object 30 is used.

本文所使用的术语“光敏光学可变(POV)安全标志”是指印刷的视觉上黑色或深灰色的携带着可机读信息且当采用较短波长的光激发时以特殊的波长范围发出荧光的标志。 The term "photosensitive optically variable (POV) security flag" as used herein refers to a printed visually black or dark gray machine-readable information carrying and when excited by light in a shorter wavelength range of a particular wavelength to fluoresce symbols of. POV安全标志在整个可见光谱范围内呈现出可见光谱的吸收,且该光谱范围包括了可见光谱中的红色区域,但对典型的自动扫描系统来说,红色的墨水是不可见的。 POV security mark present in the entire visible spectral range an absorption in the visible spectrum, and the spectral range includes red region of the visible spectrum, but a typical automatic scanning systems, the red ink is invisible. 这些墨水就可以在诸如牛皮纸或马尼拉纸的深色纸上获得可接受的PCS(印刷的对比信号)。 These inks can be obtained in an acceptable dark paper such as kraft paper or the manila the PCS (print contrast signal).

图2a和2b显示了包括数据阵列条形码的POV安全标志的机器扫描图像22和24。 Figures 2a and 2b show a machine comprising a POV security mark scan image data array 22 and the bar code 24. 在POV安全标志中可以使用诸如一维条形码、其它类型的两维条形码、可印刷的水印,或OCR特性的任何其它符号。 One-dimensional barcode may be used, other types of two-dimensional bar code, any other symbols such as watermarks, or OCR printable characteristics in POV security flag. 反射扫描的图像22是采用可见光来照明该标志所获得的。 The reflected image 22 is scanned using visible light to illuminate the sign obtained. 黑色模式的低反射率使得扫描图像的深色区域对应于安全标志的印刷区域。 Low reflectivity black mode such that the scan image corresponding to the dark areas of the printing region of the security. 以荧光扫描的图像24是通过观察在紫外(UV)照明下可见红色荧光的发射而获得的。 Fluorescence image 24 is scanned by emitting red fluorescence was observed in the visible under ultraviolet (UV) illumination is obtained. 扫描的图像24显示了当采用UV光照明时安全标志发射可见光并且使得在扫描图像中的发光区域对应于所印刷的区域。 24 shows a scanned image when illuminated with UV light and emit visible safety mark such that the light emitting area in the scanned image corresponding to printed areas. 比较图像22和24显示了荧光图像时发射图像的负像,即,在两个图像之间存在着较强的负相关性。 Comparison image 22 and 24 show an image when the negative image emitted fluorescence image, i.e., between the two images exists a strong negative correlation.

荧光图像22可以在紫外光的激发下由邮票或邮戳12或者其它安全标志14、16、18、32、34、36产生。 14,16,18,32,34,36 fluorescence image 22 may be generated by a stamp or indicia or other security flag 12 at the ultraviolet excitation. 图2b说明了当采用可见光照明安全标志时由相同安全标志所产生的可见图像24。 Figure 2b illustrates the visible image using visible light illumination 24 when the safety signs produced by the same safety signs. 图2a和2b只是作为范例,因为采用OVD墨水印刷的邮票和邮戳12或者其它安全标志14、16、18、32、34、36都可以具有吸收可见光以及在紫外光的激发下产生荧光发射的功能,并且荧光图像22和可见图像24是相互相关的。 Figures 2a and 2b as examples only, because the use of stamps and printing ink OVD indicia or other security flag 14,16,18,32,34,36 12 may have a function of absorbing visible light and the fluorescence emission of the ultraviolet light at an excitation , and the fluorescent image 22 and a visible image 24 is related to each other. 如果邮票和邮戳12或者其它安全标志14、16、18、32、34、36采用复制设备(例如,影印机)被非法复制时,通常是难以获得荧光图像的。 If the stamp 12 and the indicium or other safety sign 14,16,18,32,34,36 using copy device (e.g., copy machine) from being illegally copied, is usually difficult to obtain a fluorescent image. 为了能确认邮票和邮戳12或者其它安全标志14、16、18、32、34、36的有效性,就有可能通过荧光图像22和可见图像24的视觉比较来发现它们之间的匹配。 In order to confirm the stamp 12 and the indicium or other safety signs 14,16,18,32,34,36 effectiveness, it is possible to find a match comparison therebetween by visual fluorescence image 22 and image 24 visible. 然而,较佳的是,采用比较的设备来比较图像22和24,正如图3所示。 However, preferred is the use of the device to compare the comparison image 22 and 24, as shown in Figure 3.

对于诸如邮资付费的数值计量的应用和其它安全应用来说,其法律特征是很重要的。 For applications and other security applications, such as postage metering value paid, its legal characteristics is very important. 荧光墨水的其它安全应用包括安全纸和文件。 Other security applications of fluorescent inks include security papers and documents. 于是,即使去除了可见的深色颜色之后,所保存的荧光图像104依然可以提供印刷内容的法律证据。 Thus, even after removing the visible dark color, fluorescence images saved 104 can still provide legal proof print content. 在本发明中,在荧光和非荧光部分之间渗透上的差异提供在已经去除了可见部分之后依然存在着标志的法律证据。 In the present invention, between the fluorescent and non-fluorescent portion of the difference in penetration offers have been removed after the visible part of the law of evidence still exists sign in.

采用通用黑墨水印刷的安全标志是容易复制和改动的。 Adopt common safety signs printed in black ink is easily copied and altered. 数据的真实性的确认,例如,通过确认在条形码的数据中所包括的加密数字签名就能够检测数据的改动,而不能检测复制的数据。 Confirmed the authenticity of data, for example, by checking the encrypted digital data in the barcode included in the signature data alteration can be detected, the copied data can not be detected. 本文所披露的可机读荧光墨水提供了防止不可检测的复制的屏障。 Disclosed herein, a machine-readable fluorescent ink provides a barrier against undetectable copying. 通常,荧光是附加在有色的墨水中,以增加其亮度。 Typically, fluorescence is added to colored inks to increase the brightness. 现在还没有普遍的商业动机来制造用于一般用途视觉深色的荧光墨水,从而使得机读的荧光墨水可以成为用于特殊用途的唯一可控制的供应物件。 Yet no general commercial incentive to the manufacture of a general purpose visual dark fluorescent inks, so that the machine-readable fluorescent ink can be supplied items for special purposes only controllable.

这些POV安全标志可以采用数字打印、热传递或电子摄影术的方法来产生。 These POV security markers may be employed digital printing, thermal transfer or electrophotography method to generate. 特别是,可以采用本文所披露的水性墨水通过喷墨打印来制成。 In particular, disclosed herein can be used aqueous ink be made by inkjet printing.

图3说明了适用于确认安全标志12的系统。 Figure 3 illustrates the system is suitable for safety signs to confirm 12. 正如图3所示,可见光源50可以用于提供在安全标志12上的照明光60。 As shown in Figure 3, a visible light source 50 may be used to provide illumination light 60 on the 12 safety signs. 采用来自安全标志12的反射光70,反射图像扫描仪80可以采集可见光图像24。 Reflective light 12 from the security mark 70, the reflected image scanner 80 may capture a visible light image 24. 类似,紫外光源52可以用于提供在安全标志12上的照明光62。 Similarly, the ultraviolet light source 52 may be used to provide security flag 12 on illumination light 62. 采用来自安全标志12的荧光发射72,荧光图像扫描仪82就能够采集荧光图像22。 Fluorescence 12 emitted from the security mark 72, the fluorescence image scanner 82 can be acquired fluorescence image 22. 较佳的是,控制机制54可用于调整照明源50和52的照明以及图像扫描仪80和82所扫描的图像。 Preferably, the control mechanism 54 may be used to adjust the lighting 50 and 52 and 80 and the image scanner 82 scans an image illumination source. 反射图像扫描仪80和荧光图像扫描仪82可以分别和连续采集各自的图像。 Reflection fluorescence image scanner 80 and the image scanner 82 may each continuous acquisition and respective image. 然而,当采用适当的滤波器和光学部件将反射光70和荧光发射72直接引导到各自的图像扫描仪时,也有可能同时采集到可见光图像24和荧光图像22。 However, when using an appropriate filter and the optical member 70 and the reflected light when the phosphor 72 is directly guided to the respective emission image scanner, it is also possible to simultaneously capture the visible image 24 and fluorescent image 22. 较佳的是,将荧光图像22和可见图像24存储与一个图像存储部件84,从而能处理和比较这些图像。 Preferably, the fluorescence image 22 and a visible image memory 24 stores the image with a member 84, so that it can handle images and compare them. 正如所示,表示荧光图像22的信号和图像数据86和表示可见图像24的信号和图像数据88都可以发送到图像处理和相关设备90。 As shown, the fluorescence image signal representing the image 22 and 86 and data signals representing the visible image 24 and the image data 88 can be sent to the image processing device 90 and associated. 因为荧光图像22是可见图像24的“负”像,并且这两个图像是不同颜色的,较佳的是,在比较图像数据86和88之前,先处理图像数据86和88。 Because the fluorescence image 22 visible image 24 is "negative" image, and these two images are of different colors, it is preferable that the data before the comparison image 86 and 88, to process the image data 86 and 88. 例如,软件程序92可以用于计算表示在荧光图像22和可见图像24之间相关性的数值94。 For example, the software program 92 may be used to calculate a value of correlation between the fluorescence image 24 visible image 22 and 94. 该相关性数值94随后与预先设定的数值96相比较,以确定荧光图像22和可见图像24是否是采用印刷安全标志12的OVD墨水的结果。 The correlation value 94 is then compared 96 with a preset value to determine the fluorescence image 22 and a visible image 24 were the result of the OVD 12 by printing ink safety signs. 例如,只有如果相关性数值94是等于或大于预定的数值96,才能假定安全标志12是采用OVD墨水合法产生的。 For example, if only the correlation value is equal to 94 or greater than the predetermined value 96, 12 can be assumed that the security mark is generated using OVD ink legitimate. 应该注意的是,因为OVD墨水的荧光发射可以限制于一定的波长范围,所以就有可能使用带通滤波器,只允许在波长范围内的荧光发射72能够到达荧光图像扫描仪82。 It should be noted that, since the fluorescence emission OVD ink may be limited to a certain range of wavelengths, it is possible to use a band pass filter, allowing only fluorescence in the wavelength range of the fluorescence emission 72 can reach the image scanner 82. 正是如此,非法复制所产生的荧光发射就能被滤波去掉。 Is the case, the fluorescent emission produced by illegal duplication can be removed by filtering. 应该注意的是,以上结合图2a和3所进行的讨论只是涉及来自邮票或邮戳12所获得的荧光图像和可见图像。 It should be noted that discussed above in connection with FIGS. 2a and 3, be directed only from the fluorescence image obtained stamp or indicia 12 and the visible image. 应该理解的是,荧光图像和可见图像也能从任意安全标志中获得。 It should be understood that the fluorescence images and visible images are also obtained from any safety signs. 此外,较佳的是,在使用图像扫描仪进行扫描获得安全标志的图像时,有可能使用数字摄像机或视频摄像机来获得图像。 Further, preferably, is in the use of an image obtained by scanning the image scanner safety signs, it is possible to use a digital camera or a video camera to obtain an image. 也有可能使用胶片摄像机来获得图像,以及使用转换设备将胶片图像转换成数字图像,以便于处理。 It is also possible to use a film camera to obtain an image, and using the conversion device converts the film images into digital images to facilitate processing.
